<p>Hello everyone! Here is my attempt of using available light ... :-)</p><div></div>

<p>Narayan, beautiful picture! 50mm rules.</p><div></div>

<p>Beautiful pictures everyone!</p><div></div>

<p>Happy WedNEsDAy everyone!<br>

This is my wife's family shoe brush from 1922. Name initials and year of manufacture are embedded - 19MR22.</p><div></div>

<p>Calculator has probably already considered the crop factor. So you should put 50 mm in both examples. On <a href="http://www.dofmaster.com/dofjs.html">http://www.dofmaster.com/dofjs.html</a> results are:<br>

D700 with 50mm at 1.8 at 10 feet = 1.29 ft<br>

D300 with 50 mm at 1.8 at 15 feet = 1.94 ft<br>

In both examples Circle of confusion is 0.02 mm</p>

<p>DOF is almost the same for different focal lengths if the object is framed the same way.</p>

<p>From article in http://www.cambridgeincolour.com/tutorials/depth-of-field.htm :<br>

"Even though telephoto lenses appear to create a much shallower depth of field, this is mainly because they are often used to make the subject appear bigger when one is unable to get closer. If the subject occupies the same fraction of the image (constant magnification) for both a telephoto and a wide angle lens, the total depth of field is virtually* constant with focal length! This would of course require you to either get much closer with a wide angle lens or much further with a telephoto lens."</p>

<p>A few examples:<br>

Very interesting! I would really like to see a picture of your Linux. She could even help me to convert more Wintendo users to Linux ... :-)<br>

<p>Harvey, how did your dog get the name Linux? Linux is the best operating system for computers and other electronic devices btw.<br>

Great photos everyone!</p>

<p>Thank you for your last week's comments of my pictures!<br /> I'm looking forward to see all the beautiful pictures this week.<br /> <br /> Our company's Olympics! :-)</p><div></div>

<p>I have to agree with Richard: "Words don't take much bandwidth. I think any delay is the images." Comments (text) part of the thread 40 are 229 KB while pictures are 22 MB. So comments are about 1 percent of all load. We shouldn't spare the words, we should put lower size limit for images and somehow force that limit.<br /> <br /> There is one option for people who frequently refreshing thread only for reading the comments. They can disable automatic loading of images in web browser. That way thread loads in seconds. Maybe this is the solution for Lex also.<br>

<br /> <br /> Where's 41, I'm ready with picture only about 100 KB big! :-)</p>

<p>Nice to see your beautiful work again!<br /> Here is my contribution this week ...</p><div></div>

<p>It was beautiful WedNEsDAy again! Thank you all for your kind words. Lil, it is Afghan, 6 months old. She is very big already, even more in comparison with our other dog Yorkie! :-)<br>

Have a nice week(end) and see you next Wednesday!</p>
